4.3.1 Inspection
The following instructions apply to all radius rods
used on this vehicle:
1. Clean all parts thoroughly.
2. Inspect radius rods for distortion and cracks.
We recommend the “Magnaflux” process to
detect cracks in the radius rod. Any
damaged part should be replaced with a
new one.
NOTE
New bushings should be used when rods are
replaced.
3. The radius rod bushings should be checked
periodically for signs of shearing,
deterioration, or damage. Any defective part
should be replaced with a new one.
4.3.2 Removal
1. Flatten the tab washer which secures the
two retaining nuts (or bolts), then unscrew
the nuts (or bolts) at each extremity of the
radius rod (Fig. 42).
2. Remove the tab washer and the retaining
plates and radius rod ends from anchor
pins, and then remove the radius rod.
4.3.3 Bushing removal
1. Safely support the radius rod as shown in
figure 43.

2. Place a flat steel disc, slightly smaller than
the outside diameter of the bushing (Fig.
43).
3. Using an arbor press or a suitable driving
tool, press or drive the old bushing out of the
rod and discard the bushing.
CAUTION
Make sure to prevent the steel disc from
contacting the radius rod end.
4.3.4 Bushing installation
1. Lightly spray the inner and outer surfaces of
radius rod bushing with water.
CAUTION
No lubricant whatsoever is to be used on the
rubber bushing.
2. Safely support the radius rod, and place
new bushing on top of the radius rod end
(Fig. 44).
3. Place a block of wood on top of bushing and
press on it manually.
4. If necessary, use an arbor press or a suitable
driving tool. Press or drive the bushing into
the radius rod end until it extends equally on
both sides of the rod.
5. It is also possible to proceed differently.
Place radius rod bushing on a plane surface.
Spray a light coat of water on the inner and
outer surfaces of radius rod bushing.
6. Take radius rod, align the bushing. Tap
radius rod on bushing until latter is positioned
correctly.
